Filler Dissolving in Seoul (Hongdae): Hyaluronidase for Foreigners
Filler dissolving uses hyaluronidase, an enzyme injection that breaks down hyaluronic acid (HA) filler. It suits people with lumps, migration, overfilled areas or results they no longer like. Softening usually shows within 24–48 hours, and some cases need more than one session. A doctor first confirms the filler type and plans the correction.

How it works
Most modern fillers are made of hyaluronic acid. Hyaluronidase is an enzyme that breaks the bonds holding HA gel together, so the body can absorb it. A small amount is injected precisely into the area where the filler sits.
The enzyme starts working within minutes, and most of the change is visible within 24 to 48 hours. Dense or long-lasting fillers may need a second session. Because the enzyme also acts briefly on the skin's own HA, the doctor uses only what is needed.
The doctor will ask what filler you had, when and where. A small test may be done for allergy. Injection feels like a brief sting, and mild swelling or redness is common for a short time.

Frequently asked questions
How much does filler dissolving cost?
The cost depends on the area and the amount of enzyme needed. Send us a message on WhatsApp or KakaoTalk with photos and any details about your previous filler, and our team will share current pricing. The doctor confirms the plan after examining you.
Does it hurt?
It feels like a brief sting or pinch, similar to filler injection. Numbing cream or ice can make it more comfortable. Most sessions are short, usually around 15 to 30 minutes including preparation.
How fast does it work?
Hyaluronidase starts working within minutes, and most people see clear softening within 24 to 48 hours. Swelling from the injection can hide the result at first. If some filler remains after a week or two, a top-up session may be suggested.
Can it dissolve any filler?
No. Hyaluronidase only dissolves hyaluronic acid fillers such as Juvederm or Restylane. It does not dissolve collagen stimulators like Radiesse or Sculptra, or permanent fillers. The doctor checks your history before treatment.
When can I get new filler?
Usually after about 1 to 2 weeks, once the enzyme has finished working and swelling has gone down. Waiting helps the doctor see your true baseline and place new filler more accurately.
Can I fly after filler dissolving?
Generally yes. Mild swelling may be noticeable during the flight. Because allergic reactions, though uncommon, can appear after treatment, we recommend staying nearby for a short time and messaging us if you notice strong swelling, itching or rash.

Filler Dissolving Injections in Hongdae – Safely Reverse & Refine Your Results
Unhappy with previous filler results? Experiencing overfilling, unevenness, or migration? Filler dissolving injections offer a safe and effective solution to reverse unwanted hyaluronic acid (HA) filler—restoring your natural facial balance. At our professional clinic in Hongdae, we specialize in precise, medically guided filler dissolving treatments to help you regain control of your appearance.
What Are Filler Dissolving Injections?
Filler dissolving injections use an enzyme called hyaluronidase, which breaks down hyaluronic acid-based dermal fillers safely and efficiently. The enzyme rapidly targets and dissolves the unwanted filler, allowing the treated area to return to its original appearance—or prepare for a correctional re-treatment.
Dissolving is commonly used for:
- Overfilled lips or cheeks
- Uneven filler placement
- Filler migration or lumps
- Poor aesthetic results from previous treatments
- Vascular compromise or complications
- Preparing the area for new filler
The treatment is quick, highly effective, and fully customizable based on your needs.
Why Choose Filler Dissolving?
Key Benefits:
✅ Safe and medically approved for HA filler correction
✅ Works within minutes to days
✅ Restores natural facial contours
✅ Allows for treatment “reset” or correction
✅ Minimal downtime with quick recovery
✅ Peace of mind after unsatisfactory results
✅ Suitable for both aesthetic and emergency corrections
Filler dissolving is not only corrective—it’s empowering. Whether you want a fresh start or to refine your results, this treatment offers flexibility and control.
How Filler Dissolving Works
Hyaluronidase is injected directly into the area where unwanted HA filler is present. The enzyme begins breaking down the filler immediately, with visible softening typically occurring within 24 to 48 hours. In some cases, multiple sessions may be needed for complete resolution.
Once the filler is fully dissolved, patients may choose to leave the area natural or undergo a refined re-injection after a few weeks.
What to Expect During Treatment
The procedure takes 15 to 30 minutes, depending on the area and amount of filler to be dissolved. A topical numbing cream is applied beforehand for comfort. The injection itself may cause slight swelling, redness, or bruising, which usually resolves within a few days.
Patch testing is performed if you have never received hyaluronidase before, to rule out allergic reactions.
Who is a Good Candidate?
You may be a candidate for filler dissolving if:
- You are dissatisfied with the aesthetic outcome of a filler treatment
- You’ve experienced unevenness, migration, or puffiness
- You have filler-related complications (e.g., vascular compromise, nodules)
- You want to refine or reverse a previous filler before re-treatment
- You’re in good general health and not allergic to hyaluronidase
A personalized consultation is essential to assess the filler type and determine the right dissolving approach.
How Long Do Results Last?
Once hyaluronidase dissolves the filler, the effects are permanent for that treated product. Your body does not replace the dissolved filler. If desired, new filler can be re-injected after 1 to 2 weeks, once the tissue has settled and inflammation has resolved.
